           Summary: Implement u-boot power-off timer
           Product: OpenMoko
           Version: current svn head
          Platform: Neo1973
        OS/Version: Linux
            Status: NEW
          Severity: minor
          Priority: P2
         Component: u-boot
        AssignedTo: werner at openmoko.org
        ReportedBy: laforge at openmoko.org

If u-boot starts up, but no kernel is booted because either

1) the kernel image was invalid
2) the automatic boot was aborted by input on the console
3) 911+poweron was present to enable indefinite bootdelay

and there was no input on the serial/usb console for a specified time (let's say
three or five minutes), the phone should just power-off.

This can probably be implemented easily by adding an IRQ handler for the
PCF50606, and asking the PCF50606 to generate it's SECOND interrupt (one tick
per second) and then just count in the irq handler.
